WARNING

Lexus Safety System+

The Lexus Safety System+ is designed to reduce the effects of a collision on occupants and the vehicle when driving safely, or to assist the driver under normal driving conditions.

Because the detection accuracy and intervention behavior of the system are limited, do not rely too heavily on it. The driver is always responsible for monitoring the area around the vehicle and driving safely.

Vehicle Data Recording

The Pre-Collision System is equipped with a highly advanced computer that records certain data. This includes:

  • Accelerator pedal position
  • Brake status
  • Vehicle speed
  • Operating status of the Pre-Collision System functions
  • Information (such as the distance and speed difference between your vehicle and the vehicle ahead or other objects)

The Pre-Collision System does not record conversations, sounds or images.

  • Use of Data

Lexus may use the data recorded by this computer to diagnose malfunctions, for research and development, and to improve quality.

Lexus does not disclose the recorded data to third parties, except in the following cases:

  • The owner of the vehicle or the lessee (for a leased vehicle) gives consent
  • There is an official request from the police, a court or a government authority
  • For use by Lexus in legal proceedings
  • For research purposes, in which case the data is not linked to a specific vehicle or vehicle owner

Sensors

Two types of sensors, located behind the front grille and behind the windshield, detect the information required for the operation of the driver assist systems.

Sensoren
  1. Radar sensor
  2. Camera Sensor

WARNING

  1. Radar sensor
  2. Front grille emblem

If the front of the radar sensor or the front or back of the front grille emblem is dirty or covered with water droplets, snow, etc., clean these areas.

To clean the radar sensor and front grille emblem, use a soft cloth to avoid scratches and damage.

  • Do not attach accessories, stickers (including transparent stickers) or other objects to the radar sensor, the front grille emblem or the surrounding area.

Clean the windshield if it is dirty, or if it has oil film, water droplets, snow, etc. on it. If a glass coating agent has been applied to the windshield, use the front wipers to remove water droplets in the area of the windshield in front of the camera sensor.
